Denmark tax residency: the 183-day rule
Denmark treats you as a tax resident at 183 days in any rolling 12-month window — but the day count is only the part we can calculate. It is one of Denmark's tests, not the whole rule (see the others below). Source: Skattestyrelsen (SKAT), last reviewed 2026-05-27.
183 days isn't the only route — Denmark can also treat you as resident on non-day grounds (residence / home available + intention (primary route, ksl §1(1)(1)), danish citizen on danish-based ships, danish citizen posted abroad by the danish state). See every test below.
Spend 183 days or more in Denmark across any rolling 12-month window — the count does not reset on 1 January — and residency can attach.

How does Denmark count days for tax residency?
According to Skattestyrelsen (SKAT), you become a tax resident of Denmark once you spend 183 days or more there in any rolling 12-month window. Crucially, this is a rolling window: it does not reset on 1 January. Any qualifying span that contains enough days can trigger residency, so you have to watch a moving window rather than a fixed year.
6-month continuous stay
183 days · any rolling 12-month windowSpend 183 days or more in Denmark across any rolling 12-month window — the count does not reset on 1 January — and residency can attach.
Even without a Danish dwelling, full tax liability attaches after a continuous 6-month stay. Short holiday breaks abroad are included in the 6-month period. Once 6 months is reached, tax applies retroactively from day 1 of the stay.
What else makes you a tax resident of Denmark?
The day count is only one route. Denmark can also make you a tax resident through any one of the following — regardless of how few days you spend there. These don't depend on a day count, so Yuravia can't track them for you; weigh them against your own situation.
Residence / home available + intention (primary route, KSL §1(1)(1))
You become fully tax liable from day one if you acquire, rent, or are provided (e.g. employer-paid) a home in Denmark AND use it for purposes other than short vacation-type stays, i.e. you have a dwelling at your disposal combined with an intention to reside there — no minimum day count required.
Danish citizen on Danish-based ships
A Danish national who serves or permanently stays on board ships registered/based in Denmark is deemed fully tax resident regardless of days spent ashore in Denmark.
Danish citizen posted abroad by the Danish state
A Danish national stationed abroad by the Danish state, regions, municipalities or other public institutions remains fully tax resident in Denmark (the 'public-service' rule).
Denmark at a glance
- Tax year
- 1 January – 31 December (calendar year).
- How days are counted
- Denmark uses a residence/dwelling test plus a "more than six consecutive months" stay test rather than a strict day-count; taxation generally commences from the date of arrival, and short holiday breaks abroad are included in (do not interrupt) the six-month period, while stays abroad for employment may interrupt it. PwC does not specify a part-day-as-whole-day rule, so granular arrival/departure part-day treatment is not authoritatively defined.
- What residency means
- Full tax liability means Danish residents are taxed on their worldwide income, unless they are treated as tax-treaty resident of another country under an applicable double-taxation treaty. Where residency is triggered solely by a continuous 6-month stay, liability applies retroactively from day 1 of the stay.
- Notable regime
- Researcher/Expat Tax Scheme (Forskerskatteordningen): qualifying researchers and high earners (2026 minimum salary ~DKK 75,100/month after ATP) who were not Danish tax resident in the prior 10 years can elect a flat 27% tax (effective ~32.84% with the 8% labour-market contribution) on employment income for up to 7 years.

Frequently asked questions
How many days can I stay in Denmark without becoming a tax resident?
According to Skattestyrelsen (SKAT), Denmark treats you as a tax resident at 183 days across any rolling 12-month window (the "6-month continuous stay"). Staying under that is necessary but not sufficient — a permanent home, family, or your centre of vital interests can make you resident on fewer days.
Is the day count the only way to become a tax resident of Denmark?
No. Beyond the day count, Denmark can treat you as resident through residence / home available + intention (primary route, ksl §1(1)(1)), danish citizen on danish-based ships, danish citizen posted abroad by the danish state — any one of these can apply even if you stay well under 183 days. They don't depend on counting days, so confirm them against your own circumstances.
What counts as a day of presence in Denmark?
In most jurisdictions any day on which you are physically present — including the arrival and departure days — counts as a full day. Treating both as counted is the conservative assumption. Always confirm the exact rule with Skattestyrelsen (SKAT).
What is the official source for Denmark's tax-residency rule?
